bookConcatenating Strings in JavaScript

Let's explore some operations that you can perform with strings in JavaScript.

Concatenation

Concatenation is the process of combining two strings. This operation is achieved using the + operator:


              
1234

            
let wordOne = "Hello";
let wordTwo = "World";

console.log(wordOne + wordTwo);
copy

You can see that concatenation creates a new string by combining two words.

Note

String concatenation does not automatically add spaces. You need to manually include spaces like string1 + " " + string2.

Let's create a nicely formatted string through concatenation:


              
1234

            
let wordOne = "Hello";
let wordTwo = "World";

console.log(wordOne + ", " + wordTwo + "!");
copy

Concatenation with Assignment

The += operator allows you to add text to a string-type variable:


              
12345

            
let text = "Were";
text += "wolf";
text += "!";

console.log(text)
copy
